MAX6363LUT31+T

Overview

The MAX6363LUT31+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range up to 5.5 V and features a fixed threshold of 3.08 V. The device provides a reset timeout of 150 ms with an active-low, push-pull output. It includes manual reset functionality and battery backup switching capabilities. The component is housed in a compact SOT-23-6 package and supports surface-mount installation. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Provides precise voltage monitoring with a fixed 3.08 V threshold for reliable system supervision.
• Features a push-pull output stage that eliminates the need for external pull-up resistors.
• Includes manual reset input capability allowing user-initiated system resets.
• Supports battery backup switching to maintain power continuity during main supply transitions.

Applications

• Microprocessor system supervision
• Battery-powered portable devices
• Industrial control systems requiring voltage monitoring

Procurement Notes

Verify the exact suffix configuration against official datasheets to ensure correct threshold and output type specifications. Confirm availability status as this part may be discontinued or subject to allocation changes. Cross-reference manufacturer part numbers with distributor listings to avoid counterfeit components. Ensure packaging format matches design requirements for assembly processes.

Selection Notes

Select this component when a fixed 3.08 V threshold is required for system supervision. Consider the push-pull output if external pull-ups are undesirable. Evaluate the 150 ms reset delay against processor startup times. Verify compatibility with the target operating voltage range and temperature environment before integration into the design.

Part Context

This supervisor IC belongs to the MAX636x family of low-power monitoring circuits. It shares functional similarities with other variants in the series but differs in specific threshold voltages and output configurations. The MAX6363 variant specifically targets applications requiring a 3.08 V trip point with active-low signaling.

Replacement Considerations

Direct substitutes include MAX6363LUT31-T+ and MAX6363LUT31+T. Verify pinout compatibility and electrical parameters before substitution. Check for updated manufacturing sources if the original part is obsolete.
